Enclosure Management Location (EM_LOC) – Offset 1c
The enclosure management location register identifies the location and size of the enclosure management message buffer. This register is not implemented if enclosure management is not supported (i.e. CAP.EMS = 0).
Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
31:16 | 160h | RO | Offset (OFST) The offset of the message buffer in Dwords from the beginning of the ABAR. |
15:0 | 2h | RO | Buffer Size (SZ) Specifies the size of the transmit message buffer area in Dwords. If both transmit and receive buffers are supported, then the transmit buffer begins at ABAR[EM_LOC.OFST*4] and the receive buffer directly follows it. If both transmit and receive buffers are supported, both buffers are of the size indicated in the Buffer Size field. A value of 0 is invalid. The SATA controller only supports transmit buffer. |
